Azo-functionalized dendrimers

We report the synthesis of azo-functionalized Starburst polyamidoamine (PAMAM) dendrimers. The following three systems of azo-functionalized PAMAM dendrimers were prepared by different synthetic routes: (i) phenylazo derivatives; (ii) naphthalimide azo derivatives; and (iii) phthalimide azo derivatives. Model compounds in each system were synthesized for spectroscopic comparison. Confirmation of structure was achieved using a combination of NMR and IR spectroscopy to ascertain the functional sites (i.e., the azo and the cyclic imides), while mass spectrometry and UV-vis spectrophotometry were employed to ascertain the extent of functionalization. Substitution by the azo pendent groups increased the thermal stability of PAMAM dendrimers (TGA weight loss of the naphthalimide azo-functionalized PAMAM dendrimers up to 300°C, ca. 5%).
